My purpose is to find the related assembly code is optimized in release mode, does turn on the option of Assembler Output impact the actual optimization in release mode?

Is that correct?

Since in release mode, we can not set a breakpoint in Visual Studio 2008, so I can not stop at somewhere and see the Diassembly code.

• Select "Project"->"Settings...."
• Select the "Release" build.
• Select the "C/C++" tab.
• Select "Program Database" in the "Debug info" combo (not "Program Database for Edit and Contine").
• Select the "Link" tab.
• Select "Debug" in the "Category" combo.
• In the "Debug Info" group" tick "Debug info" and press the "Microsoft format" radio button.
• Make sure "Separate types" in NOT pressed as it sucks.
